External natural science is quite content to judge in certain realms according to this principle: a knife has to do with eating, so one goes to the razor-case for a razor and cuts up the food. That is how many judgments in natural science are formed nowadays—for example, about death. Modern natural science does not go much further with its ready-made ideas about the phenomenon of death than to call it the cessation of an organism. That is easy, for then—as is done in a grotesque way to-day by many so-called scientists—we can speak of plant death, animal death, human death, all in the same sense. That, however, is really no different from speaking of a knife and putting a table-knife and a razor in the same category. In truth, what can be called death is different in plants, different in the animal, different in the case of human beings. But because in all three a cessation of organic functions is seen, people generalise.
